We present spectroscopic properties of 22 Ly$\alpha$ emitters (LAEs) at $z = 5.5 - 6.6$ with Ly$\alpha$ luminosity $\mathrm{log}( L_{\mathrm{Ly}\alpha} \, [\mathrm{erg} \, \mathrm{s}^{-1}]) = 42.4 - 43.5 $, obtained using VLT/MUSE as part of the Middle Ages Galaxy Properties with Integral Field Spectroscopy (MAGPI) survey. Additionally, we incorporate broad-band photometric data from the Subaru Hyper Suprime-Cam (HSC) Wide layer for 17 LAEs in our sample. The HSC-y band magnitudes show that our LAEs are UV-bright, with rest-frame absolute UV magnitudes $ -19.74 \leq \mathrm{M}_{\mathrm{UV}} \leq -23.27$. We find that the Ly$\alpha$ line width increases with Ly$\alpha$ luminosity, and this trend becomes more prominent at $z \gt 6$ where Ly$\alpha$ lines become significantly broadened ($\gtrsim+260 \, \mathrm{km}\, \mathrm{s}^{-1}$) at luminosities $\mathrm{log}( L_{\mathrm{Ly}\alpha} \, [\mathrm{erg} \, \mathrm{s}^{-1}]) \gt 43 $. This broadening is consistent with previous studies, suggesting that these sources are located inside larger ionised bubbles. We observe a slightly elevated ionising photon production efficiency estimated for LAEs at $z \gt 6$, which indicates that younger galaxies could be producing more ionising photons per UV luminosity. A tentative anti-correlation between ionising photon production efficiency and Ly$\alpha$ rest-frame equivalent width is noticed, which could indicate a time delay between production and escape of ionising photon primarily due to supernovae activity. Furthermore, we find a positive correlation between radius of ionised regions and Ly$\alpha$ line width, which again suggests that large ionised bubbles are created around these LAEs, which are allowing them to self-shield from the scattering effects of the intergalactic medium (IGM). We also detect two very closely separated LAEs at $z = 6.046$ (projected spatial distance between the cores is 15.92 kpc). This is the LAE pair with the smallest separation ever discovered in the reionisation epoch. The size of their respective bubbles suggests that they likely sit inside a common large ionised region. Such a closely separated LAE pair increases the size of ionised bubble, potentially allowing a boosted transmission of Ly$\alpha$ through neutral IGM and also supports an accelerated reionisation scenario.

Simulations suggest that slow rotating galaxies are the result of galaxy-galaxy mergers that have a tendency to randomise stellar orbits. The exact pathway for slow rotator formation, however, is still unclear. Our aim is to see whether there is a relationship between fossil groups - whose central galaxies are thought to have undergone more major merging than other central galaxies – and the stellar kinematic properties of those central galaxies. We classify all galaxy groups in the GAMA redshift survey whose central galaxies were observed with SAMI as: (i) fossil groups, (ii) mass gap groups (fossil-like groups), and (iii) groups that are not dynamically evolved (NDEGs, i.e. controls). We compare the following properties of centrals across the three different group types: spin ($\lambda_{Re}$), the fraction of slow rotators ($f_{SR}$), and age. We also repeat our analysis on data from the EAGLE and Magneticum hydrodynamical cosmological simulations. In SAMI, we find that the spin parameter, slow rotator fraction, and age are broadly consistent across our three group types, i.e. the fossil groups, mass gap groups and NDEGs. We do find a weak indication that $f_{SR}$ is slightly lower for fossil group centrals as compared to NDEG centrals. In contrast, in EAGLE and Magneticum, fossil and mass gap group centrals typically have a significantly lower $\lambda_{Re}$ than NDEG centrals. Our results for SAMI suggest that the types of mergers that form fossil groups are not the types of mergers that form slow rotators. Merger count may be less important for slow rotator formation than specific merger conditions, such as the gas content of progenitors. When and where the merging occurs are also suspected to play an important role in slow rotator formation, and these conditions may differ for fossil group formation.

Understanding why people choose to adapt or emigrate when facing slow-onset climate events is central to the design and implementation of policy addressing displacement spurred by climate change, especially climate-refugee programs. In this article, we leverage extensive field interviews and a novel survey in the Federated States of Micronesia, a country at high risk of environmental degradation but whose citizens have carte blanche access to the United States. We find that despite a general awareness of environmental risks, these play a minor role in migration decision making. Instead, other factors like work, health, and family obligations take precedence.

The recent achievement of fusion ignition with laser-driven technologies at the National Ignition Facility sets a historic accomplishment in fusion energy research. This accomplishment paves the way for using laser inertial fusion as a viable approach for future energy production. Europe has a unique opportunity to empower research in this field internationally, and the scientific community is eager to engage in this journey. We propose establishing a European programme on inertial-fusion energy with the mission to demonstrate laser-driven ignition in the direct-drive scheme and to develop pathway technologies for the commercial fusion reactor. The proposed roadmap is based on four complementary axes: (i) the physics of laser–plasma interaction and burning plasmas; (ii) high-energy high repetition rate laser technology; (iii) fusion reactor technology and materials; and (iv) reinforcement of the laser fusion community by international education and training programmes. We foresee collaboration with universities, research centres and industry and establishing joint activities with the private sector involved in laser fusion. This project aims to stimulate a broad range of high-profile industrial developments in laser, plasma and radiation technologies along with the expected high-level socio-economic impact.

The Moral Foundations Vignettes (MFVs) – a recently developed set of brief scenarios depicting violations of various moral foundations – enables investigators to directly examine differences in moral judgments about different topics. In the present study, we adapt the MFV instrument for use in the Portuguese language. To this end, the following steps were performed: 1) Translation of the MFV instrument from English to Portuguese language in Brazil; 2) Synthesis of translated versions; 3) Evaluation of the synthesis by expert judges; 4) Evaluation of the MFV instrument by university students from Sao Paulo City; 5) Back translation; and lastly, 6) Validation study, which used a sample of 494 (385f) university students from Sao Paulo city and a set of 68 vignettes, subdivided into seven factors. Exploratory analyses show that the relationships between the moral foundations and political ideology are similar to those found in previous studies, but the severity of moral judgment on individualizing foundations tended to be significantly higher in the Sao Paulo sample, compared to a sample from the USA. Overall, the present study provides a Portuguese version of the MFV that performs similarly to the original English version, enabling a broader examination of how the moral foundations operate.

The regionalization of the Canadian party system is a topic that has occupied Canadian scholars for decades. While there have undoubtedly been periods of significant regionalization (for example, the 1990s) and while these periods have been well documented, there has been very little systematic study of regionalization/nationalization in the Canadian party system. We address this gap by exploring nationalization of the Canadian party system from 1867 to 2015. To do so, we apply two measures. First, we consider how nationalized party competition is by exploring the extent to which parties compete in districts across the entire country. Second, we compliment this approach by applying the Gini coefficient to vote shares, revealing the extent to which Canadian parties have (un)even electoral support from province to province. In doing so, we explore not only the system as a whole but individual parties as well.
